DTC P2185:00: ECT sensor No.2 circuit high input: Notes

DTC DETECTION CONDITION & POSSIBLE CAUSES

DTC P2185:00	ECT sensor No.2 circuit high input
DETECTION CONDITION	The PCM monitors the ECT sensor No.2 signal. If the PCM detects that the ECT sensor No.2 voltage is above 4.92 V  for 5 s  , the PCM determines that the ECT sensor No.2 circuit has a malfunction. Diagnostic support note  This is a continuous monitor (engine cooling system). The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	ECT sensor No.2 connector or terminals malfunction ECT sensor No.2 malfunction PCM connector or terminals malfunction Short to power supply in wiring harness between ECT sensor No.2 terminal A and PCM terminal 1Y Open circuit in wiring harness between the following terminals: ECT sensor No.2 terminal A-PCM terminal 1Y ECT sensor No.2 terminal B-PCM terminal 1U PCM malfunction
